Lobe pumps

Boyser is a Spanish manufacturer provide various kind of lobe pump. The operation principle of a rotary lobe pump is based on the accurate movement of its rotors, which in turn depends on the perfectly regulated synchronisation of a corresonding set of high precision gears.

The result is a positive-displacement volumetric pump with exceptional performance, which likewise allows the use of either rubberised or metallic lobe rotors, depending on the application concerned. Our design offers you a pump of compact dimensions that are well out of proportion to its displacement flow volumn, along with an ease of maintenance that really stands out with respect to other pump technologies.
